Application filed December 22, 1924. Serial No. 757,458.

g The objects of this invention are to enable small ,fu'r skins to be run through a shear ingmachine singly, rather than in a series sewed loosely together; to thus enable each 5 skin to position itself naturally and properly,without being hampered by attachment to. adjacent skins; to thus secure a perfect shearing 'of each skin and a high grade product; to simplify shearing the skins, and To provide,

particularly one which has-suitable means for mechanically holdingeacli skin on f the conveyorwhile it is presented to the shear ingknivesi. to employ such mea'ns'which" shall not interfere with or affect the shearing, and'more particularlyto use for the purpose cords which shall lie betweenthe; hairs 'to secure such I an arrangement of cords as will firmly holdeach skin while it is being sheared, as well as feed and discharge the skins, and' to' obtain other advantages and results as may be brought outby the following description. V

Referring to the accompanying drawing, in-which the same numerals of reference designate corresponding and like parts throughout the several views,

Figure 1v is an end-view of a fur shearing machine embodying my invention, individual skins beingshown one just starting onto the conveyor, another one being sheared, and a third one just. leaving the machine;; '1 H Figure 2 is a cross-section of the upper part of the machine on alarger scale;

Figure 3 is a plan'view of the middle portionof the shearing knives and means presenting a skin'thereto;

Figure 45 is a detail sectional view transver selyof the conveyor illustrating how certain cords hold the skin thereon;

Figure 5 is a plan of the'entire machine as shown in Figure 1,.and

Figure 6 is a frontelevation of the same,

In said drawings, 1 indicates an endless conveyor belt providing an apron or shelf on which the skins are fed to a cooperating stationary knife 2 and rotary knife 3, the

conveyor passing around a breast roll 4 of smalldiameter next saidshearing knives so as to sharply bend the skin and separate and extend the hairs, as is usual. In the particular fur shearing mavhine shown .for pure poses of illustration, there are side frames for 4 a 2 7 1' ar; ifFiQEg 5, 5, with forwardly projectingertensions 6, v

6 to support" a table '7 at the inner m'or which is the outer end roller 8 for the cony At; the lower partvofthe side veyor 1.

frames 5, 5 is asliaft 9 driven as by 'a belt 10 from a' suitable source of 'powen-(not' shown), and driving as by a belt ll theshaft 12 upon which the rotary blades agate "mounted; Said shaft 9 isshown having also" a pinion 13 which meshes with a gear 1410a These particular be employed without affecting my invention; Y

, The shearing knives2, 3 are enclosed 'in-a hinged to form a cover which can be opened," :7

and from the back of said casing-leads a V suction duct 19 which extends parallel to the casing and closely I adjacent thereto as" at '20" i until'it clears themachine andthen' turns downward through the-floor as at 21.

In carrying out invention applyto the inner end portion ofthe conveyor 1" or end next the shearing knives 2-, 3, 1 spaced. cords 22, also endless and traveling in'the same direction as the said conveyorri-n such relation thereto as to hold theskins'secnrely in place thereon, not only while being sheared'butalso while being fed to and dis- :charged fromthe shearingknives'. In the specific embodiment of the invention shown n the drawings, light supplemental frames 23, '23 are mounted upon the @tops of thejsilde, frames 5, 5 to carry rollers' overwhich the cords 22 pass, the direction, of inovement being forwardly over the rear and frontitop 195 I rollers 24 and 25. Fromsaid fronttop 011-1 er 25 the cords pass downwardly to a roller:

26 adjacent the top of the apron or'shelf v 7 formed by the conveyor 1 andat'aidist'ance from the inner end of said apron on shelf;

after passing this roller 26 the cords lie normally inengagementwith the conveyor. 1: forits entire inner portion passing around the breast. roll 4, being, preferably-heldlin suitable proximity to the under bight ofthe conveyor by an adjustable roller 27. at a'dis tance from the breast roll-4 andadapted'to be moved by swinging arms, 28 with frictional clamping means 29. Beneath the con veyor 1 and beyond said roller 27, the cords 22 diverge at an acute angle from, said con veyor to a roller 30 positionedsufficiently forwardso that the skins will drop clear J of the machine into a container indicated at veyor belt and the cords are free, that'i s to say, they are not inengagement with pulleys or the like andarethusfree to vibrate slightly as themachlne' is runningand shake the skin so as to detach or separate from the conveyor belt and-cause it to more positively over the pulley 30..

follow the cords 22' to its point ofdischarge' The cords 22 are throughout their length spaced suitable "distances and held parallel by grooves in the rollers asshown at '33 in I Figure 3;;t'hey aredriven by frictional contact with the portion'of the conveyor 1 which forms the inner end of the apron uponwhich the skins are fed to the machine ed in Figure 4, without depressing or fiat the skinsonto the apron or receivingshelf' formed by the conveyor, beneath the roller Y 23, 23 are open-ended 'so as to permit access or with a skin upon'said portion of the con veyor and drivenfthereby. Obviously the cords are fine enough sothat they lie betweenthe hairs of the'first skin, as illustratteningany of them andthus said hairs are freely exposed to be sheared, while an in: dividual skin is securely held against displacement. The operator has only to feed 26 and the cords passing therearound,-when said skin will pass, through the machine without further attention and bedropped off thecords as they pass over the lower frontroller 30. V V 7 By my invention, therefore, it is notneces sa-ry'to sew the 'skins'loosely'together as has been common heretofore in order to feed them -'through a fur shearing machine, the next adjacent skins to any particular skin being sheared serving to hold it in place dur-. ing the shearing operation, but the skins may be fed singly. Each skin is thus allowed to naturally assume its smooth extended position and is inothampered by attachment to preceding and following skins, and thus not only is ,less' skill required in feeding the skins to the machine but also more. perfect shearing and a better product is secured.

It will be noted that the auxiliary frames to the shearing knives, and preferably they space the rollers for the cords at a sufiicient distance from the casing 17 to enable its cover 18to be readily opened for inspection and so forth as usual. Said frames23 are of substantially rectangular shape and are arranged in the planes of the side frames5 of the machine. Obviously they may be made of any size desired to provide the neces- 1 sary'space at their endsv for access to the shearing knives for adjusting or clearing the sameof accumulated hair, enablingthe cover 18 to be freely raised for this purpose, and providing ample space for the suction duct 19 from the casing. 7

Various detail structural 'modifications may be madebythose skilled in the art in carrying outmy 'invention, without depart-' ing from the spirit "or scope thereof, and V therefore I dono't desire to be understood as limiting myself except as required by the following claims when construed in the light of the prior art; V I

Having thus descrlbed'the invention, what 7 I claim is:

1. In a fur shearlng 7 machine, the combination wlth shearlng knives and an endless conveyor having a portion over which askin is run in downward direction'andfsharply' bent for presentation to said knives, of spaced cords extending longitudinally of said 1 conveyor over-said portion and having per-1 tions extendingbackward ly above and forwardly below the same, upper and lower rollers pressing said 'cordsat 'the outer ends of their said portions'against' said conveyor at yieldable points of the conveyor, both said" rollers engaging a skin asit is sheared and holding the cords against the skin and the" skin against the conveyor, and means for driving-the said conveyor.

2. In a fur 'shearlng machine, the combi nation with shearing knives and an endless conveyor having a portion over which a skin is run in downward direction andsharp- 1y bent for presentation to saidknives, of spaced cords extending longitudinally of said ortion and having 'porconveyor over said tions extending bac wardly above and forwar'dlyfbelow the same, upper and lower rollers pressing said cords at the outer ends for adjusting the lower roller toward'and V away from the conveyorto adjust the pull onthe skin, and means'for driving the'said' conveyor.

3. In a fur shearing machine, the combination with shearing knives and an endless conveyor having a sharply bent portion for presenting a skin to said knives, ofa roller above said .coveyor and a roller below it both transverse to the conveyor and spaced from said sharply bent portion, endless cords passlng over said rollers and sharply bent, portion, open-ended frames at the top of the machine aifording access through their endsto the shearing knives,'and other rollers in said frames for leading said endless cords around said shearing knlves. r

4. In a fur shearing machine,"the combi Y of their said portions against sald conveyor l at yleldable points ofiithe conveyor, means and an endless conveyor having a sharply nation with shearing knives, a. casing for, said knives and an endless conveyor for presentmg a skin to sald knlves, of endless spaced cords extending longitudinally of that portion of the conveyor which presents the skins to the knives, open-ended frames at the top of the machine, a suction duct leading from said casing through the open bent portion for presenting a skin to said knives, of'a roller-above said conveyor, and a roller below it both transverse to the cone 'veyor and spaced from said sharply bent portion, endless cords passing over said roll-' ers and sharply bent portion of the conveyor, rectangular frames at the top of the machine substantially in the planesof the side frames thereof and having centrally open ends affording access the'rethrough to the shearing knives, and other rollers in said frames for leading said endless cords around said shearing knives.
